APPARATUS FOR HANDLING SLAG.

SPECIFICATION forming part of Letters Patent No. 735,086, dated August 4, 1903.

Application filed January 22, 1903. Serial No. 140,113. (No model.)

To aZZ whom it 77mg concern:

Be it known that I, HUGO J. GLAUBITZ, a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Apparatus for Handling Slag, of which improve-' ments the following is a specification.

The invention described herein relates to certain improvements in apparatus for handling slag or cinder from blast or other furnaces, and has for its object a construction and arrangement of parts or elements whereby the slag can be conducted away from the furnace, cast into suitable basins or pans, cooled therein, and then dumped into cars.

The invention is hereinafter more fully described and claimed.

In the accompanying drawings, forming a part of this specification, Figure 1 is a plan 'view of my apparatus shown in connection with a blast-furnace, illustrated in section. Fig. 2 is a plan View of a portion of the apparatus on an enlarged scale. Fig. 3 is a View, partially in side elevation and partly in section, of the apparatus. Fig. 4 is a transverse section of the same. Fig. 5 is a sectional elevation illustrating a modification of the apparatus. Fig. 6 is a plan view illustrating a further modification of my improve ment, and Fig. 7 is a sectional detail view of one of the basins and its pivotal support.

In the practice of my invention I provide a runner, which is preferably formed in sections for convenience of construction, erection, and repair, one end of each section 2 being secured to a shoe 3, which in turn is socured to a beam 4 of the framework, while the opposite end of the section telescopes within the end of the next adjacent section. This construction will permit of the free expansion and contraction of each portion of the runner without any change of position of the runner as a whole. In the construction shown in Figs. 1 to 4, inclusive, the runner is provided along each edge and at suitable intervals with spouts 5 for the escape of slag or cinder from the runner, which is lined with sand or coke-dust or other suitable material, as shown in Fig. 4. The flow of slag from these spouts is controlled by suitable gates 6, connected by rods to levers 7, whose outer ends extend outwardly. Pans 10 are arranged in line with the spouts on each side of the runner, said pans being provided at their sides with lugs or ears 11, rotatably supported on pins 12, which are secured in bearings 13,v

supported bybeams of the framework of the apparatus, as clearly shown in Figs. 3 and 7. As shown in the drawings, the lines or rows of pans are approximately parallel with the runner, which is slightly inclined from one end to the other, so that the slag may flow freely therealong. This relative arrangement of the runner and rows of pans is not neces sary, but may be in some cases desirable, as otherwise the slag flowing from some of the spouts might spatter considerably on account of the height of fall at one end. The pivotal supports for the pans are so arranged that the latter when empty will stand in any position-in other words, the pans are balanced on their supports; but as the axes of the pans are at one side of the median line of the pans the weight of the contained slag will tend to rotate the pans, which are held in position while being filled by means of a bail 01 handle 14, secured at one end of the pans and by a catch 15, as shown in Figs. 2, 3, and 4. When in operative position, the bails or handles will rest upon beams 16 and support the pans or molds at a slight angle, so that all overflow of slag will run into the car A. By reason of the relation described between the symmetrical center of the pans and the center of gravity they will tend to tip automatically as soon as released from the catch 15. As the pans are balanced, as heretofore stated, they can be easily drawn back to position by the operator by means of the haudle or bail14. The axis of rotation of the pans can be so located that the outer portions of the latter will be heavier, so that the pans when freed from slag will automatically return to receiving position. In the construction shown in Figs. 1 to 4, inclusive, the pans are supported so that they will turn when loaded toward the runner,and will therefore tip to discharge their load inwardly into a car A, moving on a track below the runner and rows of pans. As the pans will move with some rapidity in tipping, their outer ends will strike against the spouts of the runner, as shown in Figs. 3 and 4, and will therefore jar the contained slag out of the pans and into the car. By reference to Figs. 3 and 7 it will be seen that the lugs or ears 11 on the sides of the pan have the lower ends open and are held from movement away from the supporting-pins 12 by a bolt 17, which can be easily removed, as shown in Fig. 7. This construction is particularly desirable when it is necessary to renew or repair any one of the pans. When such repair or renewal is necessary, the overhead crane 18 is connected to lugs 30 on the pan, when the latter is tipped to the position shown in Fig. 4 and the key 17 is withdrawn, so that the pan will swing freely 0E of the supporting-pins 12 and can be readily removed and a new one placed in position. After the pans have been filled or a run of slag has been completed the pans are cooled by means of streams of water thrown against the under sides of the pans from a series of perforated pipes 19. Suit able pipes 21 are arranged on the framework, so that streams of water may be thrown on the slag contained in the pans. In order to protect the workman, wire screens 22 are arranged on beams outside of each row of pans, and streams of water from pipes 23 are caused to flow along such screens. Those parts of the framework subjected to great heat, as the beams or girders supporting the runner and pans, are preferably protected by inclosing them partially or entirely by a shell 24:, of sheet metal, as shown in Fig. 3.

In the form of apparatus illustrated in Fig. 1 the runners whereby the slag is distributed to the pans are connected by a supply-runner 25 to the slag-hole of the furnace, so that the slag may flow directly to the distributingrunners and the pan. The hot-metal runner 26 is connected by an auxiliary runner 27 to the distributing-runner 1 in order that the cinder or roughing from such hot-metal runner may be conducted to the pans. While not generally necessary, it is preferred to connect the distributing-runners with a basin 28 to receive the surplus slag in case of a very heavy run which could not be handled by the pans. In lieu of connecting the distributingrunners directly with the furnace, as in Fig. 1, the slag may be tapped into a ladle29 and conducted to the slag-casting apparatus on suitable cars or by other means, as shown in Fig. 6. As shown in Fig. 5, a single row of pans may be employed or runner having spouts on one side and the pans discharging by an outward-turning movement into the car below. Elevated platforms 30 are provided to permit the workman to watch and attend to the flow of slag along the runner and to permit access to the runner for the removal of the cooled slag.

I claim herein as my invention- 1. In an apparatus for handling slag, &c., the combination of a stationary runner provided with a series of spouts arranged at intervals along its length, gates controlling said spouts, and an equal number of pivotallymounted pans arranged to receive the slag from the spouts, substantially as set forth.

2. In an apparatus for handling slag, 850., the combination of a runner provided with spouts, gates controlling the flow of slag from the runner, a series of pivotally-mounted pans arranged to move automatically to dumping position and means for holding the pans in normal position, substantially as set forth.

3. In an apparatus for handling slag, &c., the combination of a runner provided with spouts, gates controlling the flow of slag from the runner, a series of pivotally-mounted pans arranged to move automatically when loaded to dumping and to return to receiving position, substantially as set forth.

4. In an apparatus for handling slag, &c., the combination of a stationary runner, two series of pans pivotally mounted on opposite sides of the runner, spouts one for each pan of the series extending from the runner, and gates controlling the flow of slag from the spouts.

5. In an apparatus for handling slag, &c., the combination ofa stationaryrunner formed of independently-movable sections and provided with spouts arranged at intervals along the runner and a dumping-pan arranged to receive the slag from each of the spouts, substantially as set forth.

In testimony whereof I have hereunto set my hand.
